New sequence started on both enclosures.
All packed!
Very poor visibility today, can barely see the mountains.
TL_20190619_04 (600 seconds).TL_20190619_05 (600 seconds).TL_20190619_06 (600 seconds).We connected calB tank to the GC/MS and did a run. I then analyzed our 4 ppb standard (NPL). Isoprene and benzene are in both standards. Using our NPL standard to quantify the peaks in the calB run, we get:
Isoprene: 2.3 ppb
Benzene: 3.2 ppb
In theory, we should get ~3 ppb. It’s a little low for isoprene but the order of magnitude is more than correct.
New sequence started on both autosamplers.

24hr experiment (noon on Saturday to noon on Sunday) with BVOC sampling on cartridges every other flight.
Sequence started on both autosamplers.
We tried to connected the output of the TOF calibration system to the GC/MS to analyze their diluted standard. After several hrs we realized that this is not possible because their system cannot provide an excess flow to the GC/MS.
Change GC run time from 1500 to 1900 seconds because the chromatograms are ugly after 28 minutes and they shouldn’t according to Detlev. We’ll see if that changes anything.
Update: it doesn’t change anything - back to 1500 seconds.
TL_20190610_39 and TL_20190610_40.New sequence on both enclosures.
Analysis of two bags filled with Zero Air from the tank. TL_20190610_22 and TL_20190610_24.
New sequence: GCMS_Toolik_20190610.sequence.
TL_20190610_01 is NPL (Std3 BVOC) - 600 seconds.
TL_20190610_02 is Ambient BVOC.
I want to double check if we still have leftovers of heavy compounds now that Ads B X-fer line is at 120°C.
TL_20190610_03 is NPL (Std3 BVOC) again (600 seconds) but with Bakeout temp and time = 1.
TL_20190610_04 is Trap BVOC.
The following samples are Ambient BVOC samples.

In Alaska Standard Time (GMT-9).
Note that the flow rate was 196 mL/min on the autosampler when I started the sequence. Double check the flow rate tomorrow.
Detlev and I found a way to pull the instrument forward and access the back. We disconnected all the H2O tubings and checked that water was indeed flowing: OK, the H2O pump is doing its job. After testing a few things, Detlev blew in all the tubes to check for flow resistance. The water flow rate is now a little bit higher - we might have gotten rid of air bubbles somewhere (in the PMT?). Instrument restarted at 6:05pm AST, PMT at -34.2°C.
When I do a NPL run, I have leftovers of heavy compounds on following Ambient run. Detlev realized that that’s probably because the Ads-B transfer line wasn’t heated. In the VI, sheet “Heaters & Coolers”, ‘Heat AdsB X-fer’ should be ON. Now the line is heated at 120°C (was at ~60°C before). Done at ~5pm AST.
9:20am AST:
* Autosampler #2 still running - nothing to report.
* Checked and saved data HOBO#1 and HOBO#2.
* Standard tank connected to enclosure #1: note that the tank is still closed. The heated blanket doesn’t work. The tank temperature was ~20°C yesterday at 5:45pm AST, it’s now at 15.8°C.

We’re in the process of getting started with the standard tank. Detlev injected all the compounds and the tank is ready. Tank is connected to purge line (pump sending air to enclosure).
* tank temperatuare at 20.1°C at 5:45pm local time. Should reach 40°C. Check tomorrow.
* flow rate into enclosure 24.3 L/min.
* flow rate out of tank 10 mL/min.
New sequence: GCMS_Toolik_20190607. Samples TL_20190607_01 to _03: trash, I messed up. Sample TL_20190607_04 is Std3 BVOC (NPL). Then Ambient BVOC samples.
Drained H20 several times and restarted H20 pump. Seems to be working just fine for now. PMT cooler restarted at 2:02pm AST. It still doesn’t work - I give up after several attempts. 5:22pm local time: H2O pump off, PMT cooler off, PMT HV off.
PMT temperature increased to -20°C. Tried to remove air bubbles but didn’t do the trick. I turned off the PMT HV, the PMT cooler and the H20 pump. I will try to troubleshoot tomorrow.
### Daily checks
* Lab temperature = 21.8°C, AC temperature = 65F.
* Case temperature: fast O3 = ~23.2°C, fast NOx = ~20.8°C.
* PMT temperature: fast O3 = -35.4°C, fast NOx = -20.5°C.
Removed bug air bubble in H20 tubings at ~8:40am AST, will keep an eye on PMT temperature to see if that solved the problem. Okay, temperature slowly going down.
* Drierite: OK.
* Fast O3: OK, NO flow rate OK. * Fast NOx: OK. * Gas tanks: OK. * Fast O3 laptop synchronized with time.nist.gov at 8:39am AST.

3 flights from 3:30am (local time) to breakfast. First two flights with O3 sonde only (clear gradient from ~10 to ~30ppbv). Third flight with bags as well to collected ambient air samples. Bags analyzed by Catie on TOF. The wind nearly crashed the balloon today around noon. We’ll have to fix a few things before we can lauch it again.
CO2 sensor connected to enclosure. Started collecting data around 3pm local time. Logging every 60 seconds.

In inlet system sequence, a few samples where Ambient OVOC instead of Ambient BVOC. A few chromatrograms are thus empty. I updated the sequence at ~11am local time.
Using Catie’s tanks.
* Calib B tank: samples TL_20190604_01 and TL_20190604_02.
* Calib A tank: samples TL_20190604_03 and TL_20190604_04.
I then restarted the sequence. Following samples are “Ambien BVOC” samples.

I checked HOBO data.
Detlev made changes to the method yesterday (BVOC_SCAN_SIM_190531.M): the oven stays at 120°C between samples now and decreases to 35°C when the run starts (the lower we go, the better the earlier peaks such as isoprene are). Today, we increased the max temperature of the method to 260°C instead of 250°C. Note that we did not change the method’s name, still BVOC_SCAN_SIM_190531.M.
Today we updated the SIM time segments:
We also updated the peaks for each segments:
* alkanes + CFC-11: 41, 43 (alkanes) 101, 103 (CFC-11).
* isoprene: 67, 68.
* CFC-113: 101, 151.
* metacrolein + MVK: 41, 55, 70.
* aromatics (benzene, toluene, xylenes): 78, 91, 106.
* MT: 68, 93, 121, 136.
* SQT: 204, 91, 93, 119, 69.
TL_20190601_01.TL_20190601_02 is NPL.Kaixin and Jacob collected ambient air samples in 4 different bags. Catie analyzed them on the TOF.
